We hired Xalos to repair a section of spalling concrete on the outside of our crawlspace. Andy did a great job explaining exactly what their approach would be and provided a reasonable estimate. Work was scheduled easily and completed quickly and thoroughly. Great experience from start to finish. read more

Came out and did a complete inspection at no charge! Who does that!? Turns out our house is pretty level aside from a small deviation in one area and nothing needs to be done at this time so we fully expected a fee. The inspector was very helpful and thorough- definitely call them! read more

Fast service very nice employees my go to coffee shop when I am in town truly recommend this place to my friends

The back side of our house had settled 1 - 2-1/2" in the 25 years we lived here. I called Antonio in October 2024 and he came out and gave me a couple estimates for 2 different options. He also told me he was booked through mid February. His bid was competitive, his timeframe to start in mid February was spot on, a lot of his equipment (hydraulic pumps, truck to inject polyurathane) looked brand new, his guys were professional and on time. The lead employee, Alejandro was great! He always checked in with me when he arrived and he always knocked on the door to inform me they were leaving. He was very patient as I was always asking questions about what they were doing, what was next, etc. and he was always patient answering my questions and even going to grab some of the devices being used to show me and help me understand more. They installed 12 push piers on the back side of my house along with 15 Strong Jacks under the house. 8 of the push piers involved taking out dozens of deck boards. One board broke when taking apart, they replaced it with a new board and offered to stain the new board. You can't tell that dozens of boards needed to be removed for the job as the deck looks like day 1. It is great to have our house back to level and really appreciated Antonio's honesty as he used less polyurethane to inject under a slab than he expected so he had me deduct some off the contract amount. read more

I'm so glad I found Xalos. Both Antonio (owner) and Andy (estimator/project manager) were a pleasure to work with from start to finish. We interviewed 6 foundation contractors--including some very well-known ones--and were most impressed by the thoughtful and thorough solution that Andy proposed. Their bid was also very competitive. We didn't feel like they were pressuring us like some well known foundation company and only recommended repairs that they deemed necessary. They say you can judge a company by how they handle unexpected challenges. During our foundation project, the city required more work than initially anticipated. Antonio stepped up and collaborated with us to find a creative solution for us. I truly appreciated his flexibility and willingness to work with us. Throughout the project, the crew was professional and courteous, and Andy was always available to answer my questions and walk me through the process. I work with many contractors regularly, and needless to say, I was very impressed with Xalos. I've already recommended them to my clients and will continue to do so for anyone needing foundation work. read more

Antonio and his team did a great job on my foundation support work. When they started the job, they came to work on time every day though it was raining. They worked through the rain. It was a hard and dirty work but his crew worked it well and kept the site clean as much as they could. In addition to installing the push piers, they also put stitches inside the house. They did more than I expected them to and also Antonio did the foam to lift up part of my concrete with no extra cost. Antonio kept me updated and the project was completed successfully. I am hoping the support will hold up the foundation for many years. Will report back if there is any problem in the future. read more

Wall cracks starts showing up at my new home and I suspected the cause might be foundation issues, so I called Antonio at Xalos Foundation Repair because he and his crew did an extraordinary job a few years ago at my old home. I was in a rush, and Antonio graciously accommodated a same day appointment, driving an hour and a half to my place to inspect my home. After a thorough inspection, he told me the house foundation doesn't have any issues, patiently shared his insights, and told me not to worry. I was touched by his honesty. Moreover, he didn't charge me anything for the inspection at all, which I still feel guilty about. 11/10 - highly recommended! read more

Xalos lifted the foundation of my house in Petaluma. Very happy with the results and the service. Antonio and his crew were all courteous and hard working. Gave us a lower quote than competitors. We are very glad we went with them for the job! read more

I never had any problems or complaints for this company. Top notch work. The crew did great work and was clean and finished on their time-line read more

I had foundation repair service from this company in 2020 and received a 25 years warranty . But I still have foundation settling problems after repairs. I called the company owner Antonio many times telling them I'm still having issues after I patch my dry walls, the new cracks appearing, and my family room door still settling after they trim the top. Every time they just send one guy come to check and do some adjustment on the steal supporting post and send an engineer to tell me my foundation is fine, but it never worked., I new cracks show more and more in my house.The owner refuse to do more work. Be careful with this company, they don't honor there warrenty read more

These guys are great! We had some horizontal cracking along the base of our garage. Antonio completed a thorough investigation of our property prior to listing it for sale. He found some things that our foundation expert failed to see when we moved in and provided a quick estimate for remediation. He let us know which items should be addressed first for precautionary reasons, which items to watch, and which items might be considered for longterm prevention (drainage improvements). At the end of day, we had carbon fiber straps installed in the garage location where his recommendation was made. His team was in and out in a couple of days, and the work was incredibly clean. read more

I am incredibly happy that I decided to hire Xalos for my foundation repair project at my home in Sonoma. I cannot recommend them enough. Antonio and his team are true professionals, and I don't believe any other company in the area could have accomplished what they did, especially at the cost they provided. One side of my house had detached and was essentially sliding down a hill, but now it is completely level and stable. The result is perfect and almost unbelievable, considering where it started. Background: After purchasing my house several years ago, I discovered that the foundation was cut in half, causing one side of it to slowly slide down the hill. The previous seller had covered up the issue by installing new floors. I had several foundation repair companies visit to take measurements and provide quotes. I found that other companies offered a one-size-fits-all solution of installing hydraulic piers around the entire perimeter of the house. This approach did not seem appropriate for my situation for several reasons, the most important being that their proposals would not result in a level floor due to how the slab was sliding. When Antonio and his team visited, they took the time to understand and diagnose the specific problem at hand and then devised an engineering proposal to address it. Since their solution did not require installing dozens of piers, it was also much more affordable. Another significant issue was that I needed to replace the plumbing system in the bathroom, which had to be done in the middle of the foundation project. Antonio partnered with another excellent company, North End Plumbing, and coordinated with them to complete both projects simultaneously. In addition to all this, Antonio and his team worked through several challenges and unexpected setbacks. They discovered that a previous attempt to repair the foundation had been made but ultimately failed, requiring his team to excavate a huge amount of concrete. There was also a major water leak under the house, and the Sonoma permit department threw a few curveballs as well. From my perspective, it was a mess, but Antonio put my mind at ease and handled each issue with diligence and professionalism. read more

We bought a lakefront house and the foundation had been sinking causing it to be out of level by 7 inches. We contacted Xalos Foundation Support and Antonio told us we can fix this. He was extremely professional and easy to work with and explained the whole process. Our daily crew was Arturo Junior, Bryan Z., Luis, and Alberto V., and Andy. They arrived on time, were extremely polite and kept the job site organized and clean. Arturo Jr. was the lead and answered all of our questions. The project was a success and done very quickly. We highly recommend this company. read more

Andy came to the house we were in contract to purchase. He was friendly, courteous, and professional, easy to work with. Also obviously knew what he was doing and I felt confident in purchasing Xalos's service for this foundation inspection after the initial home inspection recommended it. Andy then responded quickly to my request for his report within 24 hrs so we could meet our contingency deadline. Report was well organized and readable. It gave us the information we needed and could get no other way. This was money well spent. Our agent was impressed and said they'd save Xalos info on their list to refer clients to. read more

We couldn't be more happier with the repair xalos foundation did for us. The two guys that did the repair of our foundation did very good work, was Clean, fast and reliable and respectful. The price was reasonable as well. Thank you Andy and thank your crew as well for us. ​ read more

Had a great experience working with Xalos. Andy came out and looked at the damages to my house, and made very honest assessment that the wooden column in my house are not weight-bearing and that the damages do not impact the structural integrity of the house. Instead, I would be fine finding a carpenter and handyman to replace the damaged portion. Thanks Andy! Would strongly recommend! read more

Update: Within an hour of the review, we got a call and Antonio showed up personally the next day. Things are stable for now in my home and Antonio is getting help with answering and returning calls. I like them as people and they do great work, and if they can get the administrative part of running a business addressed, they will be phenomenal. read more

Antonio and his crew are excellent. Our house required extensive foundation repair and Antonio's assessment of the work necessary was aligned to a much larger firm, however, Xalos's pricing was tens of thousands of dollars lower. The crew was professional--always on time, courteous and tidy. The work took the estimated length of time and there were no surprises. The finished cost matched the estimate down to the penny. It was great to work with a company local to our community, who offer top-notch service at affordable rates. Highly recommend Xalos Foundation! read more

Quality , professionalism and value ! This company took the time to explain everything from the quoting point . They gave us the best price from 3 other quotes I received . Very straightforward process . Felt informed every moment and gave me the best Customer service . Permits processing was fast ! They took the time to calculate various options in order to meet our budget ! Antonio "Tony" was amazing their crew were always work and clean up , leaving no mess ! Please compare your quotes and take the time to meet with all companies , you will see the difference! read more

Before selling our house, we had a home inspection that turned up a problem with part of the foundation. I called Xalos, based on the positive reviews, to request a consultation. Antonio answered the phone right away - it's so aggravating that so many contractors go straight to voicemail, and you're lucky if you ever get a callback! He asked me to send photos from the inspection and advised me on the options for dealing with the crack in the foundation, giving approximate prices for the repairs. Many contractors will just schedule a time for an inspection, come out (eventually) and read you "the riot act" about how bad your problem is. I was so relieved that Antonio and his crew provide prompt work and fair pricing. read more

We had a few quotes done for our cracked foundation on our home in San Rafael. The owner of the company came out and did the quote himself and explained the process clearly. They were able to wrap the job up in just a couple of days and we couldn't be happier. We haven't had a single issue since. read more

Great company. Very easy to work with. We had a 70 year old home that was settling. Andy, the estimator suggested, that the old pier posts be replaced with heavy duty screw jacks to support the existing beams. On the day of the job, both Andy and his co-worker arrived on time and again reviewed what work was going to be performed. After the job was completed, they shared photos of their work. Andy also pointed our that an old galvanized drain pipe was leaking and could create some issues if not repaired. Antonio stopped buy to oversee the work and even gave a great recommendation for a plumber to repair the leaky pipe. Very Impressive!!! I would highly recommend Xalos for your foundation needs. Vince S read more

I was in need of screw Jacks to support the joists in the crawl space due to the originals being old and rusted. I called Xalos and made contact with Antonio. Antonio was very responsive and came to the house within a day. Antonio gave me a very good bid and worked with me regarding a time frame. The day of the job, Eric and Alejandro arrived and were very professional. They laid down plastic and explained the whole process that would take place. Eric checked in several times to see if I had any questions. The work was done promptly and efficiently. Also, the areas were left extremely clean. I highly recommend this company for any type of foundation work. Pleasure to deal with. read more

"These guys were amazing to work with! I would highly recommend them for any foundation work you need done.They were honest and accurate on their estimate. Andrew talked things over with me every day when they arrived, communicating exactly what was going to be done that day, and the next. He was very patient with me when I had any concerns, explaining to me in detail so I would completely understand. I just can't say enough nice things about these guys, as they were a pleasure having around. I would highly recommend them over the other companies that we spoke with about the job." read more

We use Xalos to level our house that was built in 1955 on Adobe soil, and one corner had dropped 4 inches lower than the center of the house. We had postponed having this type of service performed due to the fear of the high cost of a project like this. However, we realized that the sagging foundation was going to cause more problems in the future if we did not have it fixed. I was pleasantly surprised with how affordable the quote was, and also happy we were able to get the work done within a month or so of the original visit. When the crew got here, they were very professional and respectful of our home and yard. They also took the time to explain the steps throughout the project, and always left the site clean at the end of the day. Overall, I found this company to be very easy to work with. I really loved that I did not have to do any prep myself, the crew moved anything that was in the way, then put it back when they were done. I highly recommend this company for an affordable and professional job. read more

Antonio was extremely knowledgeable regarding foundation and structural integrity! He was able to quickly investigate and take measurements to find the root cause. Antonio provided a a couple solutions that would fix our foundation issues for a reasonable price. He was very friendly and professional. Would highly recommend using his services! read more

Antonio is outstanding. We had to change out A majority of our foundation's support Jacks, add a sump pump, add a moisture barrier, and dig out to make the crawlspace to code. He worked quickly, was fairly priced and was kind. The support Jacks have a warranty and no doubt if there were any problems, I know he would come back. When we were installing our flooring, he came back and adjusted the subfloor. He's professional and knowledgeable and great and easy to work with. Sometimes he's a little delayed in getting back to you, but always gets back to you. I would recommend him to anybody with foundation issues and needs. read more

Shopping for a company to level your house isn't a fun process. It's an expensive job and not as much fun as say, having your house painted. That said, it's an unfortunate necessity for some of us. My wife set up a number of estimates for us and we suffered through them. It's not that the estimators were bad. The price was just scary, but we'd assumed it would be costly. Our first estimate actually came from Xalos. I remember discussing it after and saying we hoped they came in cheapest because we really liked Antonio and just the general feeling he gave us about the whole project. After a couple more estimates, we found the prices to be in the same boat give or take a few thousand dollars. Xalos wasn't the cheapest. They weren't the most expensive either, but we both just had a feeling about the company. We followed our guts and went with Xalos. We didn't regret it for one second. From the very beginning we could tell this company is different from basically any other contractor we've dealt with. (Working in property management, I personally have experienced quite a few.) At the beginning of almost every day, we got a rundown of what to expect for that day. And at the end of every day, we got a review of how things were going and what to expect moving forward. The team was polite, efficient and clean. They worked at our house for just over three weeks and at the end of everyday, they left the job site pristine. They told us that their plan was to make it look like they'd never been there when the job was done. I was a tad disbelieving BUT, they did. When they left on the last day, everything looked the same as when they'd started. Actually, it looked a bit cleaner even! Over the three weeks, we got to know the guys and we were happy to see them every morning. At the end of the job, I can actually say I was sad to see them go. You will NOT be disappointed if you decide to use them. Highly highly recommend. read more

Antonio recently lifted and leveled our house. The job went perfectly! He and his crew were very friendly, and professional. They arrived on time and cleaned up at the end of each day. I would absolutely recommend them. read more

I was impressed not only with the work performed by Antonio and his team at Xalos, but also with the professionalism in which they conducted themselves. They were punctual, worked very hard each day and never left a mess. Every day I received an update on the progress being done to repair the cracked foundation and settling that affected my home. I am thoroughly pleased with the results, and would hire them again in an instant. Thank you for getting the job done Xalos! read more

We called Xalos for an estimate to help us repair our foundation. Anthony showed up in the same week we called and gave us a detailed walkthrough of what he observed and what he thinks would need us to do to get our foundation fixed. We thoroughly reviewed the proposal and asked a ton of questions before we decided to go with Xalos. A decision not regretted. On the day of scheduled construction, Erick and his crew came on time and politely introduced themselves and talked through the whole process and focused on each day's progress. Nothing happened as a surprise. Everything was just like what was described. The project went on pretty smoothly. Everyday, they showed up and worked really hard to keep on the schedule. It's amazing to see how much they can progress with no interruption to the neighbors and the house from inside. Two weeks passed, the project was finished and everything looks like nothing had happed. Two thumbs up for Xalos and Erick and his crew. I had already recommended them to my neighbor who has similar issues. read more

Antonio was prompt n professional and we appreciated his honesty/integrity. Our home showed a couple hairline fractures in a couple areas so we reached out to him based off of the reviews we read. Antonio inspected our home (inside/out)and reassured us that nothing serious is present other than the natural settling on the bearing wall. I highly recommend Antonio for anyone interested in foundation repair. read more

Antonio is absolutely a gem! He managed to squeeze us into his busy schedule and came out to look at our foundation very quickly.

When I found a crack in our slab foundation, I was very concerned that foundation repair companies would steer me to the most expensive solution possible. Antonio arrived punctually and was very friendly. He examined the crack in our foundation and said it was just cosmetic and we didn't need to do anything. I really have no idea so someone could easily have taken advantage of that. I am so relieved that Antonio was the first contractor to come out and take a look, and that he is so honest. Such a load off my mind!!!! read more

Antonio his team are simply amazing! We were selling our home and we found out we had foundation issues. He came out quoted us a price far more reasonable than any of his competitors. Worked with the city and the structural engineer so that our home could close escrow. He is knowledgeable and takes the time to get the job done right and in a timely manner; even working over a holiday weekend! Thank you Xalos Foundation support. read more

We had problems with our foundation jacks creating a high spot across the center of the house. Xalos Foundation Support came out the same day and discovered that the support jacks needed adjustment but also recommended replacement of the 44 year old jacks due to corrosion. Antonio gave an honest and fair estimate and sent his crew within days to repair. The crew was very polite ,efficient and took time to explain the process. The job was finished in one dayOur house now has flat level floors and the foundation is stronger and will last for years to come. read more

We recently ripped up some carpet and found out our subfloors were quite uneven. Antonio came out and took a look under the house at our screw jacks and let me know a few would need to be adjusted and some posts taken out. THE NEXT MORNING, his crew was out here and took care of it within an hour. Our subfloors are now level as can be! Antionio and his crew were very friendly and professional. I would highly recommend Xalos to anyone out there that has foundation concerns. read more
